Finding the Most Important Plant Upsets

ALTERNATE TITLE: Find the Most Important Process Upsets with Oscillation Significance

PlantTriage now shows the impact that cyclic upsets have on your plant's
performance. PlantTriage's new "Oscillation Significance" identifies cycling
problems in a plant, and ranks them according to importance.

Oscillatory upsets are always a problem. They cause energy losses, lower
product quality, and reduced equipment life. Oscillation Significance uses a
combination of statistical and frequency-domain information to calculate a
single, meaningful measure of significance for each process parameter.
Drill-down reporting ranks every process parameter in the plant by Oscillation
Significance.

John Gerry, President of ExperTune, says "Our customers have asked for
more tools to make use of the enormous warehouse of information within
PlantTriage. With Oscillation Significance, you can look at a single number
and evaluate a very complex cycling problem."

John Gerry continued "Using traditional approaches, solving oscillation
problems may take days or weeks. Now, in minutes, you can have a prioritized
assessment of the cycling for every part of the process."

PlantTriage Oscillation Detection analyzes every process variable in a
system, looking for patterns of cyclical behavior. It then identifies the
source of oscillation to be valve problems, tuning, or load disturbances.
Oscillation Significance further refines these assessments by using a
combination of loop variability, oscillation detection, and percent of power
by frequency. The resulting measure of oscillation detection can be ranked
directly, or in combination with economic criteria. A list of process
parameters ranked by oscillation significance is then displayed in a
drill-down report.

PID Tuning Translator Eases Conversion to New Control System (August 2005)

ExperTune's PID Tuning Translator easily converts PID tuning from one
industrial PID controller to another. It converts PID values from any of over
490 different industrial PID controllers to the new system.

For example, when migrating from a PLC to a DCS, the PID tuning parameters are
converted directly to the proper units and time bases for the algorithm
choice. This maintains the established dynamic performance of the control
loop.

John Gerry, President of ExperTune said "Customers have loudly requested the
ability to quickly transfer PID settings when upgrading to a new control
system. The Translator does that, saving time and avoiding human error".

John Gerry continued, "On a typical DCS conversion project, loop re-tuning can
take days, or even weeks. With PID Tuning Translator, all loops retain their
basis of performance, and are converted in just hours."

The software converts PID settings from any DCS, controller, or PLC to any
other DCS, controller or PLC. In addition to the included 490 PID algorithms,
you can customize your own combinations. Many manufacturers have several
different PID algorithms available, and the software also converts between
different algorithm types within a single manufacturer's controller.

Visual Mapping Gives Performance View of Entire Plant (June 2005)

PlantTriage latest release includes Visual Performance Mapping. It
shows the performance of thousands of assets on one browser screen.

With a glance, the Visual Performance Map allows management,
engineering, and maintenance to determine how the plant is performing,
and where effort is needed for improvement. By drilling down into an
asset, engineering and maintenance can view complete diagnosis of
problems.

The Visual Performance Maps include several layers of drill-down.
Users can zoom-in on specific plants within the site, and specific
unit operations within a plant. Then further drill down into specific
loops for detailed diagnosis.

All of the assets on the map are spaced into one congruent area. Each
asset is represented by both size and color of a rectangle. The
larger the size, the more important the asset. The brighter the
color, the more opportunity there is to make improvements. For
example, bright asset represents a large opportunity for improvement.

PlantTriage continues its industry leading innovation by linking
Visual Performance Mapping with biggest payback and historical
performance at a glance.

New PlantTriage Measures Profit and Performance in Real-time (April 2005)

ExperTune's new release of PlantTriage assesses the performance of batch
processes. It pinpoints areas where improvements can increase yields,
throughput, and decrease turnaround times. Once the areas are identified,
specific analysis recommendations are made to improve the control of the batch
process.

PlantTriage prioritizes areas for improvement, so personnel are focused on the
most profitable areas. It also directs engineers to the product codes where
the greatest profit improvements can be made.

A new equation builder allows assessments of batches to be synchronized to
periods within a batch when the control loops are operating. This eliminates
erroneous assessments of data during batch filling, emptying, heat-up or other
irrelevant times

PlantTriage automatically performs 46 assessments on every controller on each
batch process. Assessment and diagnosis include detecting oscillations,
non-intrusive field instrument diagnosis, controller performance, interaction
detection, process modeling, and control system availability. It connects to
automation control systems via industry standard OPC or OPC HDA.

ExperTune's new version of PlantTriage automatically sends technicians and
engineers an email if a controller or process area behaves abnormally.
PlantTriage detects problems well before they show up as an operator alarm.
Now the PlantTriage alert email will announce the potential problem in good
time for it to be fixed. Shut-downs are avoided. Product quality is
increased and production becomes more efficient.

PlantTriage alerts are easy to set up from a desktop browser. For example,
engineers may want to be alerted when a critical controller or an entire unit
operation is underperforming. Or they may wish to be alerted if a number of
controllers in a certain area start to oscillate. Plant managers may wish to
know if the variability of a critical process variable increases. Alerts are
fully flexible. Any user can choose any assessment of any loop or unit
operation.

PlantTriage includes a browser alert summary window which shows which alerts
are outstanding for which user, now and at any time in the past. This makes
sure that the alert is not overlooked until the underlying problem is
diagnosed and fixed. For documentation purposes there is a browser-based log
of when alerts occurred and returned to normal.

ExperTune's New Wizard Guides Engineers to Best Level Control (January
2005)

ExperTune has released a new software wizard to help process engineers
optimize the control strategy of level control loops in all types of process
vessels. The wizard uses the design experience of Greg Shinskey.

Level loops present a unique challenge to process control since the control
objective varies widely, from tight level control in reactors to averaging
level control in surge tanks.

Whatever the performance requirement, whether it be a complex application like
a hot vapor by-pass, or a simple surge tank, the new ExperTune Level Wizard
guides engineers through choosing and implementing the best level loop control
strategy for each individual need. The wizard:

Identifies the goals for the level loop

Chooses the level control strategy that matches the plant's goals

Finds the best P, PI, or PID parameters to meet those goals

Provides built-in user guidance (see figure below).

The wizard pays for itself quickly by:

Forcing the controls to adhere to the operational objectives,
maximizing profits

ExperTune Level Wizard optimizes level loops with the following level control goals:

Fast and accurate control of level to setpoint, with and without
derivative control action. The result is the fastest possible recovery
back to setpoint in the face of upsets.

Averaging level, where the purpose of the tank is a surge vessel
to smooth flow upsets. In this case, the vessel is used to reduce the
effects of upstream disturbances. The goal is that one unit feeding a
second should disturb the second as little as possible.

Averaging level with P action only - level is floating, maximizing
the use of the surge vessel to smooth flow upsets.

Averaging level with P and I action - level floats and slowly returns to setpoint.
